hi,

i had a small Unreal 4.27 Desktop Windows project using input from Gamepad and keyboard (not a mobile game).

After that, i have added android export to it.

But when i try to add a virtual joystick to my game, the virtual joystick is displayed but it does not respond. if i click on it with my mouse under windows, or if i touch it under Android nothing happens. Even the visual stick do not move.

i have followed several tutorials and i do not found the source of the problem.

i have try to create a new mobile project and the virtual joystick works on it if y copy my game “Touch Interface Setup” on it and if i use the same “Project setting - input”.

Is there something to do when we convert a initial Desktop Unreal Windows project to Android ?

Here is my settings:

I have found the source of the problem.
My widget UI block input to the Virtual Joystick.
If i remove my UI widget to viewport, the virtual joystick works.
i have to find how to use Virtual joystick with UI

If you still have this issue, the solution is to adjust the ZOrder value in the Add to Player Viewport node or Add to Player Screen node. Set the value to below 0
